Molecular biologists classify the functions of genes within native species but are unsure in many cases how a gene's coding might react from one species to another. In recombinant DNA technology, a "transgenic" organism is created when the genetic structure of one species is altered by the transfer of a gene or genes from another.
This could change not only the genetic structure of the modified animal and its offspring, but its evolutionary development, sensory modalities, disease propensity, personality and behavior traits among other things.
Such transgenic tinkering already exists in many parts of the world including the United States, Britain and Australia where animal eggs are being used to create hybrid human embryos from which stem cell lines can be produced for medical research.A team at Newcastle and Durham universities in the UK recently announced plans to,
"create hybrid rabbit and human embryos, as well as other ‘chimera’ embryos mixing human and cow genes."More alarmingly, the same researchers have already managed to reanimate tissue, "from dead human cells in another breakthrough which was heralded as a way of overcoming ethical dilemmas over using living embryos for medical research" (1)
In the United States, similar studies led Irv Weissman, director of Stanford University’s Institute of Cancer/Stem Cell Biology and Medicine in California to create mice with partly human brains, causing some ethicists to raise the issue of "humanized animals" in the future that could become "self aware" as a result of genetic modification. Earliest Known Hebrew Writing Discovered
This undated picture released by the University of Haifa shows an ancient inscription on a piece of pottery in early Hebrew writing. The 3,000 year-old inscription discovered at a site where the Bible says David slew Goliath has been deciphered, showing it to be the earliest known Hebrew writing, Israeli archaeologists said.
